My 1998 Park Avenue stalled. I cleaned the idle air control valve (IAC) and now it is fine.
For model year 1989 General Motors did not produce the Buick Park Avenue. The soonest production date to 1989 was the 1991 Park Avenue. The 1991 Park Avenue was offered in 3800 engine in supercharged or naturally aspirated. The part numbers for electronic control module (ECM) or "computer" will vary based on the exact engine for model year 1991s.

If motor stalls and won't restart until cooled off, check for spark, the culprit is most likely an overheated crank shaft or cam shaft senser.
Check the Park Avenue EGR valve for a clog. A clogged valve can cause a rough idle and stall at a light.
Dealer or auto parts- many improvements made since 1989
Blower motor is located on the firewall behind the engine.
